Hello,

(a+b) (a-b) = a² - b²

or a² - b² = (a+b) (a-b)

Step-by-step explanation:

3 ( (x+4)² - 9 ) = 3 ( (x+4)² - 3² ) = 3 (x+4+3) (x+4-3) = 3 (x+7) (x+1)

- (x+9)² + 1 = - ( (x+9)² - 1²) = - (x+9+1) (x+9-1) = - (x+10) (x+8)

If ABC~DEF what is the length of BC? If ABC~DEF what is the length of EF?

marysya [2.9K]

BC would equal the same as EF, they are similar. All you would have to do is figure out the pre image (BC) of EF.

Ignore the decimal pls

Tresset [83]

So if 18 + x =43, then what you need to do is

18 + x =43
-18 -18
——————
x = 25

because whatever you do to one side, you need to do to the other

Answer:

The area of the base B is equal to $770\ cm^{2}$

The volume is equal to $10,087\ cm^{3}$

Step-by-step explanation:

I will proceed to resolve the problem indicated in the attached figure.

The figure shown a inverted rectangular pyramid

The base is a rectangle

The area of the base B is equal to

$B=(35)(22)=770\ cm^{2}$

To find how many cubic centimeters of titanium are needed to manufacture one tip, calculate the volume of the figure

Find the volume of the inverted rectangular pyramid

The volume of the pyramid is equal to

$V=\frac{1}{3}BH$

we have

$B=770\ cm^{2}$

$H=39.3\ cm$

substitute

$V=\frac{1}{3}(770)(39.3)=10,087\ cm^{3}$
